在过去的二十年里，低维(low-d)物理学已经成熟成为一门重要的科学分支。通常，我们可以将具有受限维度d的系统定义为仅在一个或两个空间方向(d=1和2)上无限的对象。这样的定义包括孤立的单链或层，但也包括变化但有限厚度的纤维和薄层(膜)。显然，许多物理现象，特别是固态物理学中的现象，都属于这些范畴。作为例子，我们可以提到：·磁链或磁层(薄膜技术)·金属薄膜(均匀或非均相、晶体、非晶或微晶等)·ID或二维导体和超导体·插层系统·二维电子气(氦、半导体界面上的电子)·表面层问题(衬底上惰性气体单层的二维熔化，一般的表面问题)·He或‘He的超流体薄膜·聚合物物理学·有机和无机链状导体，·超离子导体。·ID或二维分子晶体和液晶。·ID或二维铁电和反铁电学。
In the last two decades low-dimensional (low-d) physics has matured into a major branch of science. Quite generally we may define a system with restricted dimensionality d as an object that is infinite only in one or two spatial directions (d= 1 and 2). Such a definition comprises isolated single chains or layers, but also fibres and thin layers (films) of varying but finite thickness. Clearly, a multitude of physical phenomena, notably in solid state physics, fall into these categories. As examples, we may mention:• Magnetic chains or layers (thin-film technology).• Metallic films (homogeneous or heterogeneous, crystalline, amorphous or microcristalline, etc.).• Id or 2-d conductors and superconductors.• Intercalated systems.• 2-d electron gases (electrons on helium, semiconductor interfaces).• Surface layer problems (2-d melting of monolayers of noble gases on a substrate, surface problems in general).• Superfluid films of~ He or'He.• Polymer physics.• Organic and inorganic chain conductors, superionic conductors.• Id or 2-d molecular crystals and liquid crystals.• Id or 2-d ferro-and antiferro electrics.
